StackScope records what new websites are built with, the week they launch. Most we find ourselves, by watching public internet infrastructure for brand-new sites; the rest come from Product Hunt, Hacker News and PeerPush. We crawled this one for its tech stack and scored it for launch readiness: DNS, security headers, SEO basics. This page is what we saw on 7 July 2026; the live site may have changed since.
Every technology below links to its own page: which other new sites launched with it. Vendors and agencies watch those pages with Stackdar and hear about new adopters the week they ship, from £15 a month.
Castmates: Offline AI Roleplay has the basics covered well, with complete legal pages, a thorough launch checklist, and well-configured email security. Worth fixing first: missing several security headers.
Launched on Product Hunt on July 7, 2026. The site is hosted on Vercel and served through Cloudflare, with a domain registered 6 days before launch. Our crawler found 12 technologies on this site, covering seo, analytics, CDN, and CSS frameworks. The stack includes Astro, Tailwind CSS, and Apple App Store.
It's also running the same core stack as 229 other launches.

Vibe Score Breakdown How?
| Signal | Points |
|---|---|

This score is based on structural patterns and is not definitive. Many legitimate sites may trigger signals, and AI-built sites may go undetected. It should be treated as an indicator, not a verdict.
